Answer:
5.123, 5.13, 5.3, 5.31
Step-by-step explanation:
So we tell how big a number is by starting before the decimal and moving to the right towards the direction of the decimal.
So we first see that they all are 5, so we go and look at the next one, which is the tenths. We can see that two of them are 1 tenths and the other two are 3 tenths. Using that we can tell that the two which are 3 tenths are bigger so put them aside.
Look at the two which are 1 tenths. Go to the next place value, which is the hundredths place. We can see that 5.123 has 2 in the hundreths place and 5.13 has a 3 in the hundredths place, therefore, 5.123 is the smallest followed by 5.13.
Repeat this for the other two to get 5.3 being the 3 smallest and finally 5.31 as the biggest.

Answer:
Part A: 115
Part B: 36000
Explanation:
Part A asks for the perimeter, which is adding, so add up the 15, 40, and 60, which will equal to 115.
Part B asks for the area, which is multiplying, so you multiply the numbers,
15 x 40 x 60 = <u>36000</u>
15 x 40 = 600
600 x 60 = 36000
You could try multiplying it a different way but get the same answer:
60 x 40 x 15 = <u>36000</u>
60 x 40 = 2400
2400 x 15 = 36000
I'm not sure if this is correct but I hope I helped
have a great day/night :))
Answer:
Step-by-step explanation:
∵ The volume of the pyramid = 1/3 base area × height
∵ The base is equilateral Δ with side length 4
∴ The area of the bast = 1/4 × 4² × √3 = 4√3 units²
To get the height of the pyramid draw it from the vertex of the top of the pyramid ⊥ to the base on the centro-id of the base which divides the height of the triangle two ratio 2:1 from the vertex of the triangle
∵ The height of the base = √(4² - 2²) =√12 = 2√3
∴ 2/3 the height = 4√3/3 ⇒ (2:1 means 2/3 from the height)
∴ The height of the pyramid = √[4² - (4√3/3)²] = √[16 - 48/9]
∴ h = 4√2/√3 (4√6/3 in its simplest form)
∴ V = 1/3 × 4√3 × 4√2/√3 = 16√2/3 units³
∴ 
I am pretty sure the answer is H
